azaarenes with alkyl iodines has been established through strategic modulation of N- or P-donor ligands. This method enables the synthesis of diverse β- or γ-branched aromatic N-heterocycles. The mild regiodivergent protocols exhibit wide substrate scope, excellent functional tolerance, and great reaction yield with remarkable regioselectivity. Importantly, deuterium labeling studies reveal NiH-catalyzed
通过 N- 或 P- 供体配体的策略调节,建立了氢化镍 (NiH) 催化的 2-烯基氮杂芳烃与烷基碘的迁移和非迁移加氢烷基化反应。该方法能够合成多种β-或γ-支化芳香族N-杂环。温和的区域差异方案表现出广泛的底物范围、出色的功能耐受性、高反应产率和显着的区域选择性。重要的是,氘标记研究揭示了 NiH 催化的中断链行走模式是远程 β-选择性加氢烷基化反应背后的机制,这是一种通过芳香亚胺导向基团介导的有趣现象。
